Current National Weather Service forecasts for Denver indicate a mostly clear overnight with a low near 65°F, driven by a warm late-summer air mass and light winds that limit mixing and radiative cooling. This places the expected minimum in the upper 60s range favored by market-implied odds, though exact readings depend on the timing of the daily minimum, urban heat island effects at official stations, and minor forecast adjustments from updated model runs. Historical late-August averages near 58°F highlight the current pattern's departure, while clear conditions and dewpoint trends introduce the primary uncertainty separating the closely matched 66–69°F bins from cooler or warmer alternatives.
